British Air Force Typhoon fighter aircraft have conducted a mission with French aircraft in a coordinated attack targeting an hidden munitions depot in Syrian territory used by the Daesh militant organization, as stated by the UK's MoD.
The facility, pinpointed through reconnaissance, was assessed as housing weapons and explosive materials, the statement said, and was positioned in mountains just north of Palmyra in central Syria.
"Our aircraft employed precision-guided Paveway IV munitions to strike a series of access tunnels down to the facility... initial indications indicate the objective was successfully hit," officials stated.
There was no indication of any civilian casualties in the operation conducted Saturday night and all the aircraft made a safe return, the MoD added.
The Typhoon fighters were supported by a Voyager tanker plane.
The Islamic State group - alternatively referred to as the so-called Islamic State - imposed extremist governance over parts of Syria and Iraq prior to its 2019 collapse.
"This action shows our UK leadership, and commitment to work closely with our partners, to stamp out any resurgence of Daesh and their dangerous and violent ideologies in the Middle East," the British Defence Secretary the Defence Secretary remarked.
RAF aircraft have performed overwatch operations over Syrian airspace to "prevent any attempted resurgence" of Islamic State following its defeat at the battle of Baghuz in 2019, the ministry said.
"I want to thank the personnel of our armed forces who took part in this strike for their skill and their valour," he commented. "Including them were a great many British troops on duty over the holidays. This action, to take out militants who endanger our safety, demonstrates how our armed forces are prepared to act, throughout the year, keeping Britain secure domestically and strong abroad."
